Salesforce.com's PaaS product is known as the Force.com Platform. The platform allows external developers to create add-on applications that integrate into the main salesforce.com application and are hosted on salesforce.com's infrastructure.

These applications are built using Apex (a proprietary Java-like programming language for the Force.com Platform) and Visualforce (an XML-like syntax for building user interfaces in HTML, Ajax or Flex).

The key tools are the

• Sales Cloud
• Service Cloud
• Collaboration Cloud (Chatter)
• AppExchange
• Data Cloud

Cloudalyze provides consulting, implementation and training services to help you maximize the return on your systems investment on the Force.com platform. We also provide custom staffing solutions to suit your needs.

Android is an open-source software stack for mobile devices, and a corresponding open-source project led by Google. We created Android in response to our own experiences launching mobile apps. We wanted to make sure that there was no central point of failure, so that no industry player can restrict or control the innovations of any other. That's why we created Android, and made its source code open.
